Purchase the Dirty Bird Enhanced 2-Stage Lower Parts Kit here!

Dirty Bird Industries’ Enhanced 2-Stage Lower Parts Kit consists of the highest quality, precision machined components. This LPK includes pins, springs and controls plus an extra takedown / pivot pin detent & spring set, and an upgraded enhanced polymer trigger guard.

This kit also includes Dirty Bird’s brand new 2-Stage Trigger. This trigger assembly takes advantage of a two stage fire control design that has been trusted in both competition and combat roles for decades. Springs are tuned to provide a smooth first stage pull of about 1.5lbs and a crisp second stage break at 3lb for a total pull weight of 4.5lbs (actual total pull weight may vary ± .25lb). The 4.5lb total weight gives the operator a greater level of safety and control in high stress environments but with a second stage pull weight of only 3lbs, the shooter can also squeeze off long range precision shots with ease.
